The hemoglobin A1c (HgA1c) measurement reflects the average glucose concentration over the lifespan of an RBC; its primary use is to diagnose and monitor diabetes. The two major methodologies for HbA1c measurement can produce differing results in the presence of hemoglobinopathies. Factors that alter red cell lifespan will usually lead to HbA1c results that do not accurately reflect average glucose levels. This activity addresses the uses and limitations of HgA1c measurement, and the limitations of the methods commonly used in laboratories. By understanding uses and limitations of HbA1c measurements, pathologists will be prepared to help clinicians interpret confusing HgA1c results and select appropriate tests to monitor diabetes control for patients with underlying conditions.

This clinical pathology activity is intended for pathologists.

After completing this activity, you should be able to:

  1. Describe the methods used for measurement of hemoglobin A1c (HbA1c).
  2. Compare advantages and disadvantages of the methods used for HbA1c measurements.
  3. Describe the major uses for HbA1c testing.
  4. Recognize and mitigate situations when HbA1c may provide misleading results.
